I have this item, but do not know what it is. I cannot find any hallmark on it either. The craftsmanship leads me ot belive that it is rather old.
I had trouble loading my pictures to this post, so here is a link to 4 photos of this item.
It has a removable lid that looks sort of like the plug on the underside of a piggy bank
Thank you so much for any help and insight as to what I have here…
